food shortage

事件：
China announced Thursday huge tariffs on fertilizer exports and said agricultural land was in rapid decline due to industrialization.

China's official communist news agency Xinhua News announced that export tariffs on fertilizer would increase by 100%. This will cause a virtual shutdown in the export of fertilizer from China. This is necessary to preserve fertilizer for suffering Chinese agriculture.

The fertilizer is widely used in rice, corn and wheat growing which is essential to feed the 1.3 billion Chinese. China also hopes to control rapidly rising domestic agricultural costs and inflation.

"Agricultural costs [in China] are going through the roof. Land prices, the cost of money, the relative cost of labor, fertilizer, a shortage of seeds," said Paul Schulte, of Lehman Brothers in Hong Kong. "Yet rising agricultural prices can be a windfall for those with economies of scale."
